Reinstall - No option to enter activation number

[jonathan@fomotor.com]

The Nitro  toolbar space was missing so we uninstalled and reinstalled ( 13.70.7.60) and now the PC says the trial has expired and only provides a link to the website to buy a subscription.  There is no where to enter our purchased lifetime authorization number.  No help or about menu, only preferences with no option for the number. How can we reauthorize using our purchased number?

Hello @jonathan@fomotor.com,

Thank you for reaching out to us through our Community Forums and our sincere apologies for the inconvenience.

The behavior you are receiving is commonly caused by installing a different version of Nitro PDF Pro. To fix this, kindly uninstall your current Nitro Pro through Control Panel\Programs\Programs and Features and reboot your machine.

Then please download Nitro PDF Pro 13 using these installers:

x64   https://downloads.gonitro.com/professional_13.70.7.60/en/retail/nitro_pro13_ba_x64.msi
x32   https://downloads.gonitro.com/professional_13.70.7.60/en/retail/nitro_pro13_ba_x86.msi 

To know if you have a 32-bit or 64-bit Windows system, please refer to this article:
https://support.microsoft.com/en-ph/help/15056/windows-32-64-bit-faq 

You can now activate your copy of Nitro PDF Pro by going to the Help tab > About Nitro Pro > Activate, entering your serial number, and clicking Activate.

Thank you for choosing Nitro and I hope this helps.
